HYDROCABBON Vi'iPOR-IZER'AND BURNER.

Application led I-fiay i3,

and to burnthe resulting vaporor gas. The`v burner is particularly adapted for operating upon; crude petroleum and its distillates, such as gasoline and kerosene, although it mayv be used tor burning any volatile liquid fuel. Y

The devicel is simple in construction, easy to operate, ecoiiomicalto construct, durable and eiiicient in 'oper-ation, and, in actual practice,has beenvv proven to possess great utility. F

The principle otoperat-ion ofthe burner` consists in the projection of a liquidtuel i againsta heated vaporiziiig plate, by means Otan agent underpressure, preferably superf heated steam, commingling the resulting product kwith airin a mining. chamber, and burning the resulting r'iiiXture.v

The burneras a whole is novel, and,also many ct the elemental parts thereof, asl willk Vappear from the hereinafterdetailed description of the device and its mode or op.- eration. l Y

In the accompanying drawings I have illustrated different practical embodiments ot' tlie inventioii,but vthe constructions shownv therein are to be understood yas illustrative,

Steam pipe, D, leads from a su'perheating coil, lf, which coil is located in the path of the products of combustion from cylinder, A, said coil, E, being supplied with steam through inlet pipe, F. Pipes D and E, are held in position by clamps, a' and y, respectively, cooperating vrith ring, c', secured to cylinder, A, by set screws, e. v

Near the exit end of cylinder, il, isa baille, (l, shown in the form of a plate, and provided with pei-iterations, a', said plate being secured to the cylineer through the medium of countersunlr'bolts, L. The interior of cylinder, A, has a lining` of refractory material, f, such as asbestos or fire clay, in order to protect it against melting in the event of the temperature Within the cylinder rising above the melting point of cast iron.

Referring nonT particularly to Figures 6 and '7, l have shoyvn means for operating the dampers, d', simultaneously, said moans consisting of hand Wheel, Z', operating a rod, c, to one end of which is secured a pinion, a', Which serves to move a circular rack, if, provided With internal gear teeth, j', meshing with the teeth on the pinion, n said rack having external teeth, z, meshing With teeth, f2, on dampers, d', and thereby serving to open or close said dampers. Dampers, rl', however, may, if desired, be operated individually by means of handles, (Z2, corresponding` to the handles on the dampers, ci', Figures l and s. The racl, h', isvheld in operative position by guides, jg, see Figures 6 and 7.

ln Figure 6, l have shown means for regulating the feed of oil to the burner in accordance With the pressure of steam in inlet pipe, F. This result is accomplished by means of a fluid pressure regulator, H, having a diaphragm, p, and a needle valve, a2, which valve controls the outlet, b3, of the oil inlet pipe, r, and consequently the feed of oil to the burner through the pipe, 0. rlie space above the diaphragm, 27, connects with the steam pipe, l?, by means of a branch pipe, S, sothat the needle valve, a2, is pressed downwardly to partially close the opening, 7a3, when the pressure of steam in the pipe, lf, exceeds a prcijleteruiined point. Pipe, ai', is provided with valve, s, operating handle, t", therefor, pointer, w, and dial, fv, the same as correspon-,fling elements in Figure 2.

From t-he 'foregoing description of the apparatus it is believed its mode of operation will be clear, but it may be described, briefly,

as follows: The valve in the oil pipe, i", or

source admitted to pipe, F, passes through coil, E, pipe, D, annular' chamber, and

nozel ,0, and thence to the interior of cylinde. at the same time creatine' a suction through oil pipe, r, or 0"', causing oil to be drawn up by suction through said pipe and delivered against the depression or cavity in the vaporizing plate, vili-,cnice it is drawn in the form of vapor, through openings, z', into cylinder, A; the rapidly flowing current of steam and fuel vapor entering cylinder, fr, causes air rto enter the cylinder through perforations, c, in cap, 7), resulting in the production of a mixture of steam, air and oil, or other fuel, in cylinder, A, for which reason have termed the interior of cylinder, A, a mixing chamberll; the mixture 'may now be ignited in any suitable yvay, as by infertirig a piece of ignited Wasce into the inning chan'iber through door, e.' Avery' high temperature is soon produced Withur chamber, il, thereby erving to heat the vaporiaing plate, B, and, also, the steam sus,

perheating coil,ll. 'lhe baille plate, G, serves to check the too rapid passage of the products of combustion from the mixing chamber, thereby deflecting them baclrto a certain extent upon the vaporizing plate, B, and heating said plate to a sufliciently high temperature to gasify the fuel projectedl against the cavity therein. y

The invention is particularly adapted for use on all kinds of steam boilers, though it may be used in most any location in place of solid fuel. .lt Will be noted that my *system is not a gravity system, but depends on suction or exhaustion to 'feed the 'oil tothe burner from a source of supply which may,

if desired, be located beneath the surface o-f f the grouncuthereby insuring entire YsafetyY from explosions or other accidents.

it will be understood that the several parts of the apparatus may be made of any suit-- able shape and size, to adapt them to the particular conditions of operation and that minor changes may be made in the arrange-V ment and location of the several parts \vithout departing frointhe. spirit of the invention.

Letters patent is:

ln a device of the class described, a mixl-laving thus fully described the invention, v'hat l claim as neuT and desire to secure'by ing chamber, a perforated cap for admitting airthereto, openings in said cap separate from said perforations, a plurality of shutters or dampers for admitting air through said openings, and means for operating said shutters or dampers simultaneously. I
